Abstract: Process for improving the water absorption capacity of crosslinked, water-swellable polymers by treating water-containing, finely divided polymer gels having a solids content of 20 to 65% by weight at temperatures of at least 50 DEG C with steam, the solids content of the water-containing polymer gels being increased by not more than 30% by weight and the polymer gels then being dried in a conventional manner.

Abstract: The invention relates to a method for producing polymers containing carbamate units, wherein polyethylene imines or polymers containing vinyl amine units of formula (III) in which R = H or C1-C6-alkyl are made to react with halogen formic acid esters. The invention also relates to the use of the polyethylene imines containing carbamate groups thus obtained or polymers containing vinyl carbamate units as retention agents, dehydrating agents, flocculants and fixing agents in the production of paper, as a protective colloid for the production of aqueous alkyl diketene dispersions and as a dispersing agent for the production of accumulated aqueous filling material slurries.

Abstract: The present invention relates to the use of water-soluble copolymers consisting of such characteristic structural elements as a) acrylic acid amide of the general formula (I), where R et R stand, independently of each other, for H, alkyl, cycloalkyl, aryl or aralkyl, and b) units of the general formula (II), where A represents a chemical bond or an alkyl group, the R residues stand, independently of each other, for H, alkyl, cycloalkyl, aryl or arakyl or, together with the nitrogen atom to which they are linked, an aromatic or non aromatic five to seven member heterocyclic ring, possibly mono- or polysubstituted, possibly containing one or two more heteroatoms chosen from among O, N or S, and capable of being annelated with another aromatic or non aromatic five to seven member ring, and R represents H, alkyl or aralkyl. The invention also pertains to cosmetics containing said polymers.

Abstract: This invention concerns a process for cleaning wastewater and recirculating water in paper production, de-inking and bleaching of pulp. This process involves adsorption of water-soluble anionic compounds and compounds dispersed in water from the wastewater and recirculating water onto fine-particle adsorption agents consisting of insoluble polymers which swell to a very limited extent and contain vinylamine units which have been incorporated by polymerization. This invention further concerns the use of these polymers as adsorption agents for cleaning water recirculation systems in the production of paper and for cleaning paper machine wastewater and discharge from the de-inking process and from pulp bleaching.
